Laura's water bottle holds 8 fluid ounces. How many times can she fill her water bottle with 4 quarts of water?
Hint: There are 32 fluid ounces in 1 quart.
___ times
There are 32 fluid ounces in 1 quart. Therefore, 4 quarts is equivalent to 4 * 32 = <<4*32=128>>128 fluid ounces.
Since Laura's water bottle holds 8 fluid ounces, she can fill her water bottle 128 / 8 = <<128/8=16>>16 times. Answer: \boxed{16}.
